Leviticus 14:1

XIV.

(1) And the Lord spake unto Moses. — The regulations for the purification of the leper are delivered to Moses alone, who is to communicate them to Aaron and his sons, whilst the rules by which the distemper is to be discerned were given both to Moses and Aaron. (See Leviticus 13:1.) The reason for this is probably that Moses was designed by God as the great law-giver and teacher of the priesthood as well as of the laity.
